My picture of Hercules Globular Star Cluster Messier M13. It's located in constellation Hercules and about 22.000 light years away from Earth. The cluster counts a couple of hundred thousand stars.
The picture was taken on August 10th, 2022 and it was my first time using Sharpcap for polarallignement. As a result my guiding error reduced significally and up to 0,23 pixels.

Exposure: 12x180s with darks, bias, flats, darkflats and binning 2x2
